GAEPENTERS PLANE.

Application filed January 26, 1927. Serial No. 163,687.

This invention relates in general to carpenters planes, and more particularly to carpenters planes for planing vertically extending surfaces such as the edgw of flooring and the like.

Among the objects of the present invention it is aimed to provide. an improved carpenters plane in which the cutting edges of the blades do not project from the supporting surface of the plane but project from the edges of the tool to form a plane that is particularly adapted for use with flooring.

To this end the present invention aims to provide an improved blade carrier comprising an open frame having openings extending through the body of the frame to reduce the weight of the frame to a minimum and to reduce the supporting surface to a minimum, thereby in turn to reduce the friction to a minimum.

Among other objects of the invention it is aimed to provide an improved handle for a plane of this character adapted to be supported by the two hands of the operator, which handle is arched to conform to the natural positionof the hands and thus pro tect the wrists of the operator from undue strain.

Among other objects it is also aimed to provide an improved means for anchoring the cutting blades in place on a plane of this character. To the latter end, it is a specific object of the present invention to provide blade receiving grooves in the frame of the tool, anchoring plates having tail pieces to engage the blades, and a screw having a beveled neck to cooperate with the anchoring plates to jam or wedge the tail piece into engagement with the blade and thus lock it in position on the frame. 7

The present invention still further aims to 7 provide deflecting lips or plates for. receiving the chips or shavings as they are cut by the blade and deflecting then upward and outward both out of engagement with the work and the cutting blade.

These and other features, capabilities and advantages of the present invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the tool;

Fig. 2 is a plan of'the tool with portions thereof broken away; I

Fig. 3 is an end elevation of the tool;

Fig. 41 is a section on the line 1-4 of Fig. 2;

Fig. 5 is a section on the line 5-5 of Fig. "I;

Fig. 6 is a section on the line 6-6 of Fig. 2.

The tool consists essentially of a main frame portion 1 having a guide piece 2 and a handle 3 attached thereto. Themain frame, as indicated in Fig. 2, has openings at formed therein whereby the weight of such frame is reduced to a minimum and the'surface 5 reduced to a minimum, in turn to minimize the friction created by the surface 5 during operation of the tool without impairing the eiiiciency thereof. The handle 3, as particu larly illustrated in Fig. 1, has two grip portions 6, 6 which are arched relative to the tool to receive the two hands of the operator so that the tool can be operated by the two hands of the operator and protect the wrists of the operator from undue strain.

The present tool is particularly adapted for use in laying flooring such as parquet flooring, in which the blade 7 projecting from the edge 8 of the tool is used for cutting the tongue portion of the flooring orouter edge of the flooring, and the blade 9 of the edge 10 spaced from the surface 5 of'the tool is used for cutting the groove'of the flooring.

The frame member 1, as illustrated in Fig.

2, is. preferably provided with two parallel I slots 11 and 12 to receive the cutting blades 7 and 9, as illustrated, with their cutting edges projectingfrom the edges 8 and 10 respectively.

Means for locking the blades 7 and 9 in place on the frame 1 will now be described. Two locking plates 13 and 14 are provided. The locking plate 13 has a tail piece 15 and an orifice 16, which orifice 16 has a beveled surface to receive the beveled neck 17 and serve as a cam to cooperate with the beveled neck 17 of the screw 18. .The screw 18 has a shank portion 19 engaging the threaded orifice 20 of the frame 1 and a head 21 registering with the orifice 22 of the second plate 23. The locking plate 14, similar to the locking plate 13,-is provided with a tail piece to engage the blade 9 and the orifice 24 which has a beveled surface to engage the beveled neck of the screw 25, the screw 25, similar to the screw 18, engaging a threaded orifice in the frame 1 and having itshead engaged in an orifice formed in the second plate 23. The second plate 23 is provided with two additional orifices to receive the screws 26 and 27 which enter orifices formed in the frame 1 and thus anchor the second plate 23 to the frame 1 and incidentally thereby form a guide to aline the blades 7 and 9 in place. lhe screws 18 and 25 cooperate with the locking plates 13 and 1e and the second plate.

23 to anchor the blades 7 and 9 in place, see particularly Fig. & where the screw 18 is shown with its beveled neck 17 engaging the beveled surface of the orifice 16 with the locking plate 13 to wedge the tail piece 15 against the blade 7 and securely anchor the blade 7 between the tail piece 15 and the frame 1.

Nith this arrangement, the blades 7 and 9 may be secured in place when projecting a greater or less extent as desired. The screw 18 or 25, depending upon the blade to be adjusted, is turned to release the locking plate in engagement therewith to relieve the blade, whereupon the blade can be adjusted and the screw again turned home to anchor the loclc ing plate in place without removing the second plate 23. The second plate aforesaid serves not only to aline both blades in their respective slots and thereby in proper position for cutting, but by engaging the upper surfaces of the locking plates also serves to maintain such locking plates in proper position for engaging the cutting blades.

With planes of this character, especially for use in laying flooring, difliculty has been encountered in removing the chips and shavings out of engagement with the blades and the path of movement of the bearing surface 5. To this end, the present invention provides deflecting surfaces. For the blade 7 the deflecting surface 28inclines upwardly from the bearing surface 5 and continues into the flaring surface 29 of the pocket adjacent to the blade 7. The flaring surface 29 continues around into engagement with the side of the blade 7 From the foregoing, it will be seen that as chips are formed by the blade 7, they will be deflected away from the blade 7 by the flaring surface 29, and if they engage the deflecting surface 28 they will be deflected upwardly and out of the path of movement of the bearing surface 5. The blade 9 is provided with a deflecting surface 30 similar to the deflecting surface 28 at the bottom ofthe pocket formed adjacent to the cutting blade 9 similarly to deflect upwardly any chips that might engage such surface and therefore deflect them out of the path of movement of the supporting surface 5. Similarly, the surface 31 adjacent to the surface 30, will deflect outwardly away from the blade 9 any chips that might pass to it,

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of the inventionas set forth in the appended claims.
